You are given two solutions containing different purified dnas. one is from the bacterium p aeruginosa and has a gc composition of 68%. whereas the other is from a mammal and has a cic composition of 40%. you measure the absorbance of light of each solution as a function of increasing temperature. which solution has the higher tm and why? after melting the two solutions, mixing them together, and allowing them to cool, what would you expect to happen? would appreciable amounts of the bacterial dna be found associated in a helix with mammalian dna? explain.
